The return of a breakout star. Byeon Woo-seok is heading back to the small screen with MBC's upcoming Friday–Saturday drama The 21st Century Grand Prince's Wife.

Set to premiere in April, the series stars Byeon Woo-seok as Prince Ian, the late king's only younger brother. Born the second son of the royal family, Ian has lived by concealing himself within the limits of his status—yet he is regarded as the most beloved royal.

After his brother's death, he serves as regent for his young nephew who ascends the throne. As political opposition tightens, an unexpected proposal arrives: a contract marriage from a conglomerate heiress of commoner status.

The offer disrupts Prince Ian's carefully controlled life. A source teased, "Please watch how a man who has lived with his inner fire hidden will write his fate."

New stills were unveiled alongside the announcement. Byeon Woo-seok appears transformed as Prince Ian—working and reading in a tailored suit, his presence unbroken even in moments of leisure.

His authority is also on display. Standing at the center of the palace, influential figures bow their heads, raising intrigue over the royal marriage that could decide the court's future.

Anticipation builds for a new side of the actor. Following his turn as a sincere romantic lead in Lovely Runner, expectations are high for Byeon Woo-seok's take on a modern-era prince.

The 21st Century Grand Prince's Wife tells the story of a woman who is a chaebol yet remains a commoner, and a man who is the king's son but possesses nothing—setting the stage for an unconventional royal romance.
